For ordinary skilled in the art, the specific meaning of the above terms in the present utility model can be understood according to specific circumstances.

[0031] As shown in the drawings, Figures 1-3 In one illustrative embodiment of the present utility model tidal spiral mobile piling platform, the tidal spiral mobile piling platform includes platform body 1, cross 7 and the pair of spiral propulsion assembly 4 arranged, the longitudinal one end of platform body 1 carries piling equipment 2, cross 7 is arranged on the top of platform body 1 along the transverse, the pair of spiral propulsion assembly 4 is symmetrically arranged in the transverse two sides of platform body 1, and the spiral propulsion assembly 4 includes propeller mounting bracket 41 and spiral propeller 42, the top of propeller mounting bracket 41 is connected to the transverse end of cross 7 through vertical lifting leveling piece 5, and vertical lifting leveling piece 5 drives propeller mounting bracket 41 to lift relative to platform body 1, spiral propeller 42 is rotatably connected to the bottom of propeller mounting bracket 41, and each spiral propeller 42 is connected with driving motor for driving spiral propeller 42 to rotate forward and reverse.

[0032] The spiral moving piling platform on the beach, the spiral propelling assemblies 4 are connected to the two sides of the platform body 1 through the vertical lifting leveling devices 5, when the beach surface fluctuates greatly, the spiral propelling assemblies 4 can be independently driven to lift relative to the platform body 1 through the vertical lifting leveling devices 5, so as to ensure that the spiral propelling assemblies 4 are always in contact with the beach surface, thereby ensuring that the spiral moving piling platform on the beach stably travels on the beach surface, and after reaching the piling position, the platform body 1 can be leveled by independently driving the spiral propelling assemblies 4 to lift relative to the platform body 1 through the vertical lifting leveling devices 5, thereby ensuring the verticality of piling. In addition, the spiral propelling assemblies 4 of the spiral moving piling platform on the beach are driven to rotate forward and reverse through independent drive motors, so that the platform body 1 travels longitudinally by the same direction rotation of the spiral propelling assemblies 42 on the two sides of the platform body 1 in the transverse direction, and turns by the forward rotation of the spiral propelling assembly 42 on one side of the platform body 1 in the transverse direction and the reverse rotation of the spiral propelling assembly 42 on the other side of the platform body 1 in the transverse direction; thus, the spiral propelling assemblies 42 of the spiral moving piling platform on the beach are driven by independent drive motors, which facilitates the control of traveling and turning.

[0033] In order to facilitate the control of the lifting of the spiral propelling assemblies 4, as shown in Figure 3 , the vertical lifting leveling device 5 is a hydraulic oil cylinder, the hydraulic oil cylinder extends and retracts in the vertical direction, the cylinder body of the hydraulic oil cylinder is fixedly connected to the transverse end of the cross frame 7, and the extension end of the hydraulic oil cylinder is connected to the top of the propeller mounting frame 41.

[0035] In order to further improve the traveling performance of the spiral moving piling platform on the beach on the beach surface, in the embodiment, the distance between the adjacent spiral blades 421 of the spiral propeller 42 is preferably 1.2 m. If the distance between the adjacent spiral blades 421 of the spiral propeller 42 is too small, the spiral blades 421 are easy to stir the silt when the spiral propeller 42 rotates, which leads to too small gripping force of the spiral propeller 42 and the inability to travel.

After the beach spiral mobile piling platform reaches the piling position, the support column 6 is lowered to stably support the platform body 1 on the beach surface, so as to fix the position of the beach spiral mobile piling platform and avoid movement of the platform body 1 during piling. Meanwhile, when the beach spiral mobile piling platform is turning, the support column 6 is lowered to stably support the platform body 1 on the beach surface, and then the spiral propeller 42 on one lateral side of the platform body 1 is driven to rotate forward and the spiral propeller 42 on the other lateral side is driven to rotate reversely, so as to realize turning of the beach spiral mobile piling platform in situ. Preferably, in the embodiment, the support column 6 is two, and the two support columns 6 are located at the middle of the platform body 1 and close to the two lateral sides of the platform body 1. It should be noted that, during piling, both of the two support columns 6 are lowered to improve the fixing effect, and during auxiliary turning, only one support column 6 is lowered. It should be further noted that the support column 6 can be controlled to be raised and lowered by hydraulic oil.

[0037] As shown in Figure 1 and Figure 2 As shown, in the embodiment, the piling device 2 comprises a pile frame 22, a pile hammer 21, a winch 24 and a traction rope 23, the pile frame 22 being arranged at the longitudinal end of the platform body 1, the winch 24 being installed on the pile frame 22 and close to the bottom of the pile frame 22, one end of the traction rope 23 being wound around the winch 24 and the other end being connected to the pile hammer 21 after being wound around the top of the pile frame 22. In the embodiment, the pile frame 22 is supported, the traction rope 23 is retracted and released by the winch 24 to drive the pile hammer 21 to be raised and lowered, so as to realize piling operation.

[0038] As shown in Figure 1 The platform body 1 is provided with a transverse moving guide rail 3 extending in the transverse direction, and the pile frame 22 is slidingly connected to the transverse moving guide rail 3 to move relative to the platform body 1 in the transverse direction, so that when the beach spiral mobile piling platform is in place, it is only necessary to roughly align the piling position, and then the pile frame 22 is moved relative to the platform body 1 in the transverse direction to accurately position the pile frame 22. Meanwhile, when the pile spacing is less than the transverse width of the beach spiral mobile piling platform, the pile frame 22 can be moved relative to the platform body 1 in the transverse direction to realize piling construction at multiple pile positions.
